A school supply company produces wooden rulers and plastic rulers. The rulers must first be made, and then painted. [list] [*]It takes 20 minutes to make a wooden ruler. It takes 15 minutes to make a plastic ruler. There is a maximum amount of 480 minutes per day set aside for making rulers. [*]It takes 5 minutes to paint a wooden ruler. It takes 2 minutes to paint a plastic ruler. There is a maximum amount of 180 minutes per day set aside for painting rulers. [/list] Use the system of inequalities from Example 3 to give a possible solution to the system.
[list=1] [*]Use what you know about the constraints on the real-world situation to determine any limits on the possible solutions. [*]Choose a value for [i]w[/i] and solve the first two inequalities in the system for [i]p[/i]. [*]Interpret the results.
